Key result
The 31 mm cryoballoon is linked to ~73% less RF ablation vs 28 mm with similar recurrence.
Why the study?
Does the 31 mm cryoballoon improve PVI lesion area and prevent 1-year atrial tachyarrhythmia recurrence compared to the 28 mm cryoballoon in patients undergoing atrial fibrillation ablation?
Does the 31 mm cryoballoon improve PVI lesion area and prevent 1-year atrial tachyarrhythmia recurrence compared to the 28 mm cryoballoon in patients undergoing atrial fibrillation ablation?
The introduction of a 31 mm cryoballoon expands eligibility for cryoablation in patients with larger pulmonary veins, creating larger lesions with similar 1-year efficacy to the 28 mm balloon.
May expand cryoballoon use in patients with large pulmonary veins; extends eligibility and leaves open randomized validation.

Yoneda et al. (2026) studied this question. The 31 mm cryoballoon decreased the need for radiofrequency ablation due to large pulmonary veins from 30.7% to 8.3% (p < 0.01), while maintaining similar 1-year arrhythmia recurrence rates.
